CUTTING-WIRE.

Specification of Letters Patent.

Patented Nov.9, 1915.

- Application filed May 19, 1914. Serial No. 839,623.

To all whom it may concern.

Be it known that I, BENJAMEN SCI-ILUB, a citizen of the United States, residing at Canton, in the county of Stark and State of Ohio, have invented new and useful 1mprovements in Cutting-Wires, of which the following is a specification.

The invention relates to the wires employed in brick and tile cutting machines for severing a column or mass of clay or other similar plastic or semiplastic material, I

into bricks, tiles or other sections; and the object of the improvement is to form a plurality of loops on one or both ends of the wire, for engaging the hooks of the cutting machine, in such a manner as to increase the strength of the loops and the wire stem adj acent thereto.

When the wire is bent to form a single loop with its free end coiled around the stem of the wire adjacent to the loop, the same is generally broken by the tensile, torsional and vibratory strains imposed upon the wire in actual use, long before the cutting portion of the wire is worn out, thus requiring a premature renewal of the Wire.

The object of the present improvement is attained by forming a double loop on the end of the wire, the first one of which is secured or anchored to the stem of the wire by a series of coils before the second loop is formed; and the second one of which is secured or anchored to the stem of the wire by a series of coils, either upon or beyond the first series of securing coils.

The invention, thus set forth in general terms, is illustrated'in the accompanying drawings forming part hereof, in which Figure l is a fragmentary section showing the upper and lower bars of a brick or tile cutting machine, with the Wire brackets thereon and a wire connected thereto; Fig. 2, a fragmentary perspective view showing the formation of the first or single loop on the end of the wire; Fig. 3, a similar view, showing the formation of the second loop thereon; and Fig. 4, a similar view showing the securing coils for the second loop com pleted on the stem of the wire.

Similar numerals refer to similar parts throughout the drawings.

The stem 1 of the wire is bent at or near its end to form the primary loop 2, the free end of the wire being wrapped around the stem a number of times to form the securing or anchoring coils 3 thereon at the inner end of the loop. The wire is then bent and extended forward along the side of the primary coils 3, to form the secondary stem 4, as shown in Fig. 2. The secondary stem 4 is then bent to form the secondary loop 5, and the free end of the wire is then preferably wound one or more times around the primary coils and secondary stem to form the-intermediate coils 6 as shown in Fig. 3; after which it is wound around the main stem 1 of the wire to form the secondary coils 7 beyond the primary coils 3 as shown in Fig. 4, thus forming an anchorage on the main stem of the wire for the secondary coils.

It will be understood that the particular arrangement of the intermediate coils 6 and the secondary coils 7, illustrated and described herein is not essential to the broader feature of the invention, which consists in anchoring the primary loop to the main stem by a series of coils, before the secondary loop is formed. It is also obvious that three or more loops can be formed successively in the same manner as described herein for two loops, in which event each loop will be anchored to the main stem, before the next loop is formed. The double loops thus formed are engaged on the hooks 8 and 9 of the wire brackets 10 and 11 of the upper and lower bars 12 and 13 of the cutoff table, the tension of the wire being maintained by the spring 14 in the usual manner; and it has been found that the double loop formed and secured on the ends of the wires, as described herein, prevents a breaking of the wire in the loop, or in the stem of the wire adjacent thereto, and permits the wire to be used until the cutting portion thereof is worn out in service.

The use of the series of coils illustrated and described herein as the means for securing the loops to the Wire stem, is a very convenient and efficient means for making this anchorage; but such securing means are not essential to the broader features of the invention set forth herein.

I claim:

1. A stem of wire or the like having a plurality of loops formed thereon, one loop being anchored to the stem before the next loop is formed.

2. A stem of Wire or the like having a plurality of loops formed thereon, one loop being anchored to the stem by one or more coils before the next loop is formed.

3. A stem of Wire or the like having a double loop formed thereon by first bending a primary loop with one or more anchoring coils around the stem and then bending a secondary loop with one or more anchoring coils around the stem.

4., A stem of Wire or the like having a double loop formed thereon by first bending 10 a primary loop With'one or more anchoring coils around the stem and then bending a secondary loop With one or more coils around the anchoring coils of the first loop.
